Global warming: G lobal warming is the increase in the temperature of the earth
Temperatures today are 0.74 °C (1.33 °F) higher than 150 years ago Scientists say that the temperature will rise about 3.7 °C (6.7 °F) more in 100 years
Warmer temperature will cause the sea level to increase. Rain and snow amounts will change. Some areas will get more rain, while some get less. Sea ice and glaciers will melt. Deserts will increase in size in some areas and decrease in others. Colder areas will warm faster than warm areas. Strongstorms will become more likely and farming will not make as much food. These effects will not be the same over the entire Earth. The changes from one area to another are not well known.
A pollutant is any substance that, when in an environment, poisons our air, land and water. Chemicals have poisoned all of the world, harming humans, wildlife, and plant life, on land, sea and air. Approximately 100,000 synthetic chemicals are now on the market, with one thousand new chemicals are added yearly.Air Pollution Fatalities Now Exceed Traffic Fatalities By 3 To 1.The World Health Organization reports that 3 million people now die each year from the effects of air pollution.

http://www.buzzle.com/articles/causes-and-effects-of-land-pollution.html causes of this problem: Increase in urbanization - Increase in agricultural land - Domestic waste - Agricultural activities - Industrial activities
Effects:exterminates wild life - acid rain kills trees and other plants -vegetation that provides food and shelter is destroyed. - vegetation that provides food and shelter is destroyed -pesticides can damage crops; kill vegetation; and poison birds, animals, and fish. Most pesticides kill or damage life forms other than those intended. For example, pesticides used in an effort to control or destroy undesirable vegetation and insects often destroy birds and small animals. Some life forms develop immunity to pesticides used to destroy them.
Then say some steps for this problem.
I´ve found this link i think its have a lot of information, Juan(i dont know if this is the place to put the information)
http://dsc.discovery.com/convergence/planet-earth/guide/mountains.html: this is a really good link, it summaraizes the importants points of the earth information and it is in order so it's easier to find the information. The information they give it has been taken from a tv serie called Planet Earth.
http://en.wikipedia.org/wiki/The_Earth#Tectonic_plates
I will speak about one of the most interesting things you can talk about the land: Tectonic plates. They are movements that occur over millions and millions of years, and the movements do not change regardless of what man does on earth.
